一种有机聚硅氧烷树脂的制备方法
摘要：
本发明公开一种有机聚硅氧烷树脂的制备方法，其包括以下步骤：(1)以烷氧基有机硅烷、封端剂和酸性化合物作为制备原料；(2)所述制备原料投料后搅拌均匀，所述封端剂、烷氧基有机硅烷和酸性化合物的投料摩尔比为0～40：1：0.2～5；(3)调节温度在40～150℃以进行2～20h的缩聚反应；(4)所述缩聚反应结束后将反应混合物调节至中性，然后纯化反应产物，得到有机聚硅氧烷树脂。本发明的有机聚硅氧烷树脂的制备方法具有生产过程环保无污染、能耗低、周期短，以及产物收率高等优点，并且利用本发明所生产的有机聚硅氧烷树脂具有更优良的性能。
摘要（英）：

The present invention discloses a method for preparing organopolysiloxane resins, comprising the steps below: (1) use alkoxysilane, capping agent and an acidic compound as raw materials; (2) mix all the raw materials till uniform, herein capping agent, alkoxysilane and acidic compound have a mole ratio from 0 to 40:1:0.2 to 5; (3) polycondensation reaction occurs on temperature 40˜150° C. in 2˜20 h; (4) adjust the condensation product to neutral, and obtaining a product of organopolysiloxane resin after purification. Preparation of organopolysiloxane resins with the present invention method has benefits on less environmental pollution, low energy consumption, efficient productivity, high yield of silicone resin with excellent performance.
